The quest for miniaturization of interventional devices and the integration between external surgical platforms and internal therapeutic tools are continuously fostering research in the biomedical field. Operating in the cardiovascular system poses dramatic challenges, but it also represent the elective application for highly targeted therapeutic devices.
In this paper we present a robotic platform for treating
vascular obstructions. It integrates a system for locomotion and navigation based on magnetic dragging and ultrasound
tracking, a therapeutic module which involves mechanical
attack to the obstruction by means of high intensity focused
ultrasound, and a collection/retrieval module exploiting
magnetic nano-particles to bind the obstruction debris and to
drag them to a safe region for removal. Here we illustrate the system overview and the technical and theoretical instruments for developing the overall platform; preliminary results, together with future planned works, are reported in order to demonstrate the feasibility of the proposed approach.
